Title: Material filling method for foam molding machine
Inventor: OMORI JUICHI
IPC: B29C44/00
Filed: 1987-12-25
Abstract: PURPOSE:To enable reduction of equipment expenses and simplification of the equipment, by filling a material from a material tank into a mold cavity together with air pressurized thereby to accelerate the filling speed of said material, with no necessities required for large devices related to said air pressurized. CONSTITUTION:A core mold 5 and a cavity mold 6 are so pressed as to form no crevice therebetween, so that the pressurized air, etc., don't escape directly from the inside of a cavity 11. When a regulating valve 2 is opened, the compressed air is led inside a material tank 1 from a compressor. Thus, the material inside the material tank 1 is in a pressurized state. Then, the material in the tank 1 is, together with the pressurized air, sent by pressure to a material supply port 12b of a material filling device 12 through a packing hose 34. The supply port 12b is opened when the material is filled because a plunger is retreated. The pressurized air introduced from outside accompanies the material. The material as it is being pressurized, is forcibly sent together with the pressurized air into the cavity 11 from a material outlet 12a of the filling device 12 to be filled.

Title: Cylindrical storage battery
Inventor: NAKAMARU HISAO
IPC: H01M50/528
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To enable output/input with a heavy electric current by forming a rib-shaped projecting piece, which is integrally arranged downward in an opposed edge part of a cutout hole and a cutout part arranged in a current collector and is welded in a partially biting-in state by crossing a tip part of one pole plate. SOLUTION: A rib-shaped projecting piece of a current collector 7 is arranged integrally by being bent downward in an opposite edge part 7d of a cutout hole 7b and a cutout part 7c. According to this, when a pair of welding electrodes are applied, a welding current flowing to an outside plate part 7a is little by the rib-shaped projecting piece, and that most of the welding current is concentrated on a part of the rib-shaped projecting piece. Therefore, since the rib-shaped projecting piece melts in a state of biting in an exposed core material part at respective points where the rib-shaped projecting piece and the exposed core material part cross each other, this part becomes strongly welded. Therefore, internal resistance of a battery is lowered, so that a heavy electric current can be taken out adequately.
